I'm sure that there is a term for this, but the basic premise is that anytime you are driving, you should be going only as fast as is safe. If it is foggy and you can't see more than 10 feet in front of you, you need to slow down so that you have enough time to stop if anything appears 10 feet in front of you. If it is snowing, you need to leave enough distance and go only so fast so that you can stop if anything is in the road that you need to avoid. Basically, the circumstances are irrelevant. You always must leave enough room or ajust your speed so that you can avoid anything.
In this case, there was already a warning (the OP blew his horn and swerved) that something was not right ahead. There should have been plenty of time for the guy behind him to avoid the car pulling out. The buy behind the OP was definitely at fault for at least 50% of the accident.
